2SC3324, 2SA1312, 2SC4883 and 2SA1859 are either unobtanium now, or very difficult to get.
Anyone interested in building this anew need to look for alternative devices.

Good price!
Almost tempted!
The link provided by Patrick is to my humble copy of this amp. I used D44H11/D45H11 output devices and originally specified 2SC3324, 2SA1312 for small signal.

@trung have you matched the small signal transistors?
The 2SC4883 and 2SA1859 are not matched I presume?

The 2SC4883 and 2SA1859 I bought a while ago from DK are quite well matched.
Very narrow band of hfe around 140.

You will find it worth upgrading from D44/45.
